Heavy Metals Status of Soil Around Waste Dumpsites in Ughelli Metropolis, Delta State

Ojebah C. K.*, Uwague A., Edema O. G.

This study investigated the heavy metal status of soils around waste dumpsites in Ughell, metropolis, Delta State, Nigeria. Two different dumpsites were used for this study. For the metal analysis, soil samples were collected at 0-15cm depth. The soil samples were air dried for five days and sieved. 2.0g of the soil sample was digested with HNO3/HClO4 mixture and analysed for heavy metals (Fe, ...

Evaluation of Compacted Black Cotton Soil – Sawdust Ash Mixtures as Road Construction Material

Yohanna P.*, Mannir I., Osinubi K. J.

This study was aimed at the evaluation of the stabilization potential of sawdust ash (SDA) on black cotton soil. Soil samples were treated with up to 10 % SDA content by dry weight of soil compacted with reduced British Standard light (RBSL) energy. Index properties of the natural soil showed that the soil belongs to A-7-5 (36) in American Association of State Highway Transportation Officials (AAS...

Household electronic wastes (E-wastes) generation and management in Nigeria

IBRAHIM F. B*

The rapid turnover in technology in developed and developing countries like Nigeria, has created a new environmental problem in electronic waste (e-waste) management due to high obsolesce rate of consumption. Households are one of the major consumers of electronic equipment and consequently the major sources of electronic wastes (e-waste). In this study, an assessment of the sources, types, lifesp...

Effect of Woven E - Glass Fibre Loading on the Mechanical, Morphological and Physical Properties of Reinforced Polypropylene Composite for Automobile Application

E. Danladi*, Mamza P.A.P, Yaro S. A, Isa M. T, Sadiku E. R, Ray S. S

This research investigates the impact of glass fiber content on the mechanical, morphological, physical, and dynamic mechanical properties of polypropylene (PP) composites. The selection of PP and glass fiber is driven by their widespread availability, favorable mechanical characteristics, and cost-effectiveness. The study involves the fabrication of glass fiber-reinforced PP composites using a Ca...

Geological and chemical characterization of Amethyst mineralization in Dutsen Bakura hill, Kaduna State, Northcentral Nigeria

Solomon R. A.*, Ibrahim A. A., Magaji S. S.

Dutsen Bakura hill amethyst mineralization is located within a sheared granitic gneiss in the Pan African basement complex of northcentral Nigeria. The zone of mineralization is within a shear zone that trend NE-SW consistent with Pan-African structural trend. Mineralization consists of bands of milky quartz and amethyst, apparently formed from two stage sequence of silicification. Major, trace ...

Green Synthesis and Characterisation of Magnetite Nanoparticles Using Factorial Design of Experiment

Olasupo Olayode Adesola*, Abdulkareem Ambali Saka, Kovo Abdulsalami Sani, Abubakre Oladiran Kamardeen

Magnetite nanoparticles have been produced by green synthesis method. Aqueous extract of Mangifera indica leaves was used as reducing agent for co-precipitation of magnetite from iron (II) and iron (III) salts 3 in 1:2 molar ratio. Optimisation of the process was carried out using 2 factorial design of experiments taking into consideration stirring time of reaction medium, temperature and volu...

Effect of groundnut shell ash on the particle size and plasticity characteristics of black cotton soil

IJIMDIYA T. S*

The paper presents the results of a laboratory study on the effect of groundnut shell ash on the particle size distribution and plasticity characteristics of black cotton soil. Black cotton soil was treated with a maximum 10 % groundnut shell ash by weight of dry soil. The results show that there was a substantial reduction in the amount of fines content with higher doses of groundnut shell ash...

Evaluation of Abrasion, Biocompatibility and Degradation Behavior of Polypropylene/Sugarcane Bagasse Ash Particulate Composites for Dental Application

R. M. Dodo*, IBRAHIM ABUBAKAR IBRAHIM, BelloKamilu A, Asuke F., Abdullahi Ibrahim, Shamsu Mohammed

This study reports abrasion, biocompatibility and degradation behavior of Polypropylene (PP)/Sugarcane Ba gasse Ash Particulate (SBAP) composites for possible application as dental implant materials. PP composites  were prepared with varying weight per cent of SBAP ranging from 10 – 50 wt% at regular interval of 10. Hard ness test and wear analysis were conducted. Degradation test was performed us...

Eco-acoustical evaluation of agricultural and environmental wastes as sustainable materials for noise control in buildings

Mudashir Gafar*

On a global scale, sustainable environment and noise pollution are of serious concern in most developing countries, and Nigeria is no exception. Notable scholars have studied many materials - natural and synthetic - for noise control in buildings. Sustainable environment evolves from the production, application and use of sustainable products. A product is considered sustainable if the materials u...
